Hexadecimal value support for attributes

Hi,
In Attributeregistry(http://redfish.dmtf.org/schemas/v1/AttributeRegistry.v1_3_4.json), Attributetype is allowed to have integer(copied AttributeType, AttributeValue deails from schema at end of thread)
How to add Hexadecimal value in Integer type for an attribute? Also Json is not supporting Hexadecimal value, so in this case do we need to use string and convert internally to integer values. 
In BIOS some values were hexadecimal, so user will expect same Hexadecimal value in Attribute also. Please share details related to schema or specification to handle hexadecimal values

Thanks,
Mani
